How many grams of NaOH are there in 187 grams of an aqueous solution that is 7.06 % by weight NaOH.
Answered by DrBob222
7.06% w/w NaOH means 7.06g NaOH in 100 g solution. So in 187 g there will be
7.06g NaOH x (187/100) = ?
or if you want to do it by the factor method it is
187 g solution x (7.06g/100g) = ?
